Refueling vehicle at gas station.

Jim Davidson, author of “75 Ways To Save Gas” never met a drop of gasoline he didn’t want to squeeze.

While you and I are stretching our gas bucks by keeping our tires properly inflated, taking it easy on the accelerator and setting the cruise control to 55 MPH, Davidson’s parking at the mall with his front pointing out so he can drive straight away when he’s finished shopping rather than wasting gas on reverse before the engine warms up. He also keeps his ride washed and waxed, because, he says, "a smooth, clean car can use up to 5% less fuel than a dirty one.”

Overkill, you say? Maybe. But considering the fact that the cost of a regular gallon recently reached $4.39 at a Citgo in the Bronx, some of Davidson’s gas-saving tips make a lot of sense. Here are five.

Search for deals on gas: "There are many ways to find bargains on gas," Davidson says. "And they don't all require driving around in your car late at night. Apps and websites are an excellent way to plan your next fill-up." Davidson recommends GasBuddy.com. http://www.newyorkgasprices.com/ is also a good resource.

Don't install fuel-saving devices: There are a plethora of miracle additives, gadgets and gizmos on the market, all of which claim to increase gas mileage. Leave the whizzers on the shelf. "The EPA have tested a number of these items and found that they either don't work or the fuel savings are grossly exaggerated," says Davidson.

Don't rev the engine: "Whether it's cold or warm outside," Davidson says, "Never rev the engine when you start it." With today's computerized systems, "You are overiding the programmed start procedures of your car, which will end up burning a lot of fuel and potentially damaging the engine."

Use the right fuel for your car: "Most cars run on regular gasoline," says Davidson. "So there is no need to pay more for mid-grade or premium gas. Many people buy premium thinking they're helping the engine. But they're not."

Service, service, service: "Properly servicing your car is key to its performance and longevity," says Davidson. "But most importantly, you'll save a lot of fuel over your car's lifetime if you treat it well."
